\subsection{Preprocess -- Debias and Gain}
The debias and gain stage removes a bias frame (if available), subtracts off the overscan region, and multiplies each frame by the gain.
\subsubsection{Input}
Given an observation file \verb|ifuyyyymmdd_hhmmss.fits| and a \verb|bias.fits| file, this code will subtract off the bias frame, and then remove the overscan. The code also sets the units of the frame to $e^-$ ($ADU \times GAIN$).
\subsection{Output}
\verb|b_ifuyyyymmdd_hhmmss.fits| which has been debiased and degained.
